Abstract

Development of sustainable machining processes and technologies for manufacturing of the leadless free-cutting brass parts has been widely taken under consideration due to the legislative actions restricting the use of toxic lead in industry. In this study, the two-dimensional (elliptical) ultrasonic vibration-assisted turning (UAT) was employed to machine the newly designed Cu-35Zn-1.89Al leadless free-cutting alloy. Machinability of the alloy was compared to conventional continuous turning (CT) in terms of cutting forces, chip morphologies and surface roughness. The effect of process parameters of cutting speed and feed rate was also investigated during CT and UAT. It was found that UAT had the ability to reduce the energy consumption by 47.5 percent compared to CT. Results of the machinability evaluation showed that the resultant force was reduced up to maximum amount of 60.3 percent by using UAT. The UAT process could also promote the surface roughness between 28.3 and 37.2 percent in comparison with CT.
